Etude et simulation des convertisseurs statique AC-AC et DC-AC

Abstract

This work present the comparison between three structures of two-phase inverters; a three-level inverter and five-level inverter. The comparison is based on the evaluation of the total harmonic distortion THD of the two inverters controlled by the controlled pulse width modulation strategy (PWM), we also studied a structure of three- for different firing angles. All inverters are modeled and simulated using the Matlab-Simulink-Sim Power Systems, results simulation are presented and commented.
